Software Craftsmanship 2010

Today i had a great day at the Software Craftsmanship 2010 conference at Bletchley Park. Despite getting up ridiculously early, and feeling somewhat ill during the day, i managed to have an excellent time, learn a few things, and chat to some wonderful, interesting people.

I enjoyed Jason Gorman’s enlightening tutorial on refuctoring – the art of incrementally changing code a little at a time, so that the tests still pass but it becomes less readable and less maintainable, to the point where only you have a clue what the code does. Sometimes known as Mortgage Driven Development, because it claims to ensure you keep your job. Jason encouraged to look for Code Smiles (well-written, elegant code) and refuctor them away effectively. I enjoyed pairing with Gavin on making the ugliest “Hello, World!” we possibly could!

As an antidote to the refuctoring, several people went to the workshop on beautiful, maintainable, Designer Code by Chris, however i chose to attend Michael Hunger’s Game of Life session. After the recent code retreat at eden, i was eager to learn more about the Game of Life and Michael showed us a video of John Conway talking about the Game of Life, and an implementation of the Game of Life in APL which is mind-blowingly awesome! I worked with Chris and Iain to do a version of the Game of Life in Java. I think we had an hour to do it, and we very nearly got something that worked, except we weren’t calculating the neighbours correctly so every cell died, prompting us to rebrand it as The Game of Death!

A special highlight of the day was the guided tour of Bletchley Park where we saw the places where secret codes were intercepted and decoded in World War II, and saw the impressive machines that were built to apply brute force to crack the encoding strategies. What impressed me most was how innovation was driven forward by necessity, and it made me smile to learn that the codebreaking was usually made possible thanks to stupid mistakes that were made by those transmitting the codes.

With a nod to the Lorenz encoder and the Colossus code breaker, eden launched the Minisculus Challenge today. I hope a few people have already tried the challenge and are enjoying it as much as i did! It was hard keeping it a secret last week, when i really wanted to tweet about it!

In the afternoon I went to David Laing’s workshop on Functional Kōans. I paired with Adam and together we did the kōans in javascript, learning quite a few tricks along the way.

I had a very good day, and i thank Jason, all the workshop facilitators, and everyone who helped to make the day such a success!
